Hello,
I''m configuring my linux server with puppet open and is ok. My question
is
the next; I''ve a declared in mi nodes.pp the next:
[.............]
node ''basenode'' {
include ''baseos''
include ''motd''
import ''useradd.pp''
}
#All nodes for my domain
node /.*\.example\.com/ inherits basenode {
}
[.............]
All nodes inherit basenode, Inside the class "baseos" i''ve
declared the
archive host table and various other parameters
[.............]
file { "/etc/hosts":
ensure => present,
owner => root,
group => root,
mode => ''664'',
source =>
"puppet:///modules/baseos/hosts",
}
[.............]
But I need add other node in nodes.pp and this need apply the class baseos
but without /etc/hots because this use other hosts table that I declared as
follows:
[.............]
node ''newnode.example.com'' inherits basenode {
file { "/etc/hosts":
ensure => "file",
source => "puppet:///modules/baseos/newnode/hosts",
mode => "644",
}
}
[.............]
But when I go newnode and run puppet give error for duplicate
"/etc/hosts"
declaration
[.............]
Error: Could not retrieve catalog from remote server: Error 400 on SERVER:
Duplicate declaration: File[/etc/hosts] is already declared in file
/etc/puppet/modules/baseos/manifests/config.pp:21; cannot redeclare at
/etc/puppet/manifests/nodes.pp:55 on node newnode.example.com
[.............]
How I can assign different tables hosts for different nodes in this case?
Thanks.

Hello Mike,
Here the baseos file[/etc/hosts] resource get propagated to all the
nodes because of inheritance. You again changing the same file in
"newnode.example.com" again.
Puppet does not allow to edit the same file twice (same resource again) in
single run.
Work around to that,
Create a new folders for each node in baseos module as per node name and
put node specific "/etc/hosts" file in that folder.
e.g
baseos
node1.example.com
- hosts
node2.example.com
- hosts
node3.example.com
- hosts
newnode.example.com
- hosts
All nodes inherit basenode, Inside the class "baseos" i''ve
declared the > archive host table and various other parameters

> [.............]
>
> file { "/etc/hosts":
> ensure => present,
> owner => root,
> group => root,
> mode => ''664'',
> # source =>
"puppet:///modules/baseos/hosts",
>
source =>
"puppet:///modules/baseos/$hostname/hosts",
Add $hostname facter as above in source parameter.
This will add dynamic nature to source.
Source attribute resolve to
- puppet:///modules/baseos/node1.example.com/hosts
- puppet:///modules/baseos/node2.example.com/hosts
- puppet:///modules/baseos/node3.example.com/hosts
- puppet:///modules/baseos/newnode.example.com/hosts
depending upon the node(host) name.
Hope this will solve your problem.

Implicit in all of the above is this:do not assign a class to a node if you don''t want all the resources it declares. (There is a last-ditch workaround for that, but it would cause you more harm than good at your level of Puppet experience.) There are multiple ways to go about those, but I hesitate to suggest specifics without understanding why the new node is an exception to your general rule.

Re: [Puppet Users] Re: Duplicate declaration for files.
Hello,
I fix "the problem" with a case statement:
[...............]
class baseos::rhel-hosts {
case $fqdn {
''new-node.example.com'': {
file { "/etc/hosts":
ensure => present,
owner => root,
group => root,
mode =>
''664'',
source =>
"puppet:///modules/baseos/new-node/hosts",
}
}
default: {
file { "/etc/hosts":
ensure => present,
owner => root,
group => root,
ensure => "file",
source =>
"puppet:///modules/baseos/hosts",
mode => "644",
}
}
}
}
[...............]
Thanks.

Just my 2 cents... is better if you use stdlib -> concat function for /etc/hosts... you can have a default section for all the hosts and a customized one for specific cases. You avoid conflicts as well.
